Already signed in to iD but had to create a different additional id to get into this!
How come i couldn't use the help hub with my existing iD log in details, but had to create a separate one, which isn't made clear. my password wasn't recognised so eventually I opted for 'forgot password' so I could enter the competition, waited for the reset email which never came!! now ive created a separate log in for the Help hub, the competition is closed aaah! I had the winning answer too.
